Forget full-body scans, which are currently being touted as the Next Big Thing™ in security in the wake of the Christmas Day Nigerian crotchbomber. We can't even be sure they would have stopped him.

If only

If only they would spend this effort doing something useful, they could eliminate car accidents, heart attacks and cancer, instead of trying to eliminate the statistically insignificant chance of dying in a terrorist attack.

It seems to me like the real application of these techs is in advertising, having knowledge of the subconscious behavior of an individual, you could push whatever you want on them.

AI?

One problem with all this AI behavioural monitoring is that until an actual terrorist is monitored by the system the system is unlikely to know what to look for. Yes, it certain behavioural aspects can be programmed into the system, but how do the developers know that that means someone is a terrorist as opposed to someone who has a paranoia about flying. It's still better to have actual well qualified well paid humans doing the monitoring. It's also good for the human monitors to be occasionally tested to make sure that they don't get too complacent looking for the very small numbers of problem passengers. This includes drug dealers, kidnappers, etc as not everyone is a terrorist.

The invention of print, however, made it easier to manipulate public opinion, and the film and the radio carried the process further. With the development of television, and the technical advance which made it possible to receive and transmit simultaneously on the same instrument, private life came to an end."
